everyone else has been posting about them. I have an 06 FX4 Supercrew with 71,000 miles. The2 tanks of gas prior to the plug change include Sea Foam. I drove my truck home from work last night(15 miles), pulled it in the garage and immediately started on the plug change. First I blew all of the dirt and debris off of the motor to prevent anything from falling into the spark plug hole. With the motor still HOT, I pulled all of the plugs out without a problem(no serious binding or squeeking). I did not use penetrating lube, PB Blaster, WD-4, or JB-80. Every plug broke free and came out without a problem. The first turn was easy and when it started to bind up, I would tighten the plug up a quarter turn and then continue it back out. Total time was about 1 ½ hours(I had a few distractions). This is the second plug change I have done without a problem. The first was a few month ago on my brothers 05 Supercrew that had 70,000 miles. With his, we followed the TSB. Plugs were broken free the night before and soaked with PB Blaster over night. The next morning we removed all of them with out a problem. They made a bunch of racket, but all came out with out a problem. In my opinion removing the plugs when the motor is hot without penetrating lubricant is the better approach. I am not too sure what is going wrong with the failed plug changes that I have read about, but it was a normal plug change to me. Has anyone else done the plug change with the motor still hot?

Congrats on two successful removals. Last time I checked the odds were about 85 percent against all eight coming out.

The guy that trained me on the plug removal recommends the engine be luke warm. Not cold, not hot. All eight of mine came out too. But I had a secret weapon...

The general consensus among engineering type is that the less carbon in your combustion chamber the better the chance of trouble-free removal, so either run a high detergent Top Tier gas (google "Top Tier" to see which brands are ) or run a couple tanks of gas with a known combustion chamber deposit remover. Chevron Techron is one and Shell V-Power is another. BG 44K too, if it hasn't changed since I checked last. I have no personal experience with any others but a "fuel injector cleaner" won't necessarily do it. It has to say it will remove intake valve and combustion chamber deposits. It's the carbon buildup holing the plug in.

Thanks. I use Costco gas(87). The thermal properties of the metals are your friend. I will try to post a picture later, but the end portion of the plugs were coated with a rust colored powder. I am going to be helping a friend with his plugs in a few weeks. I plan on removing them with the motor still hot. Maybe this method will help swing the odds in favor of all eight plugs coming out.

Well, Costco isn't on the latest Top Tier list, but the rusty colored electrode is a sign of a high level of detergent additives in the gas. You used Seafoam, right, so that could be it. I'm not at all familiar with that product at all. Bottom line two for two is pretty good. Maybe you need to head for Vegas!

Well it sure is good to read some success stories instead of the gloom and doom that seems to be the norm. I bought an 04 back in the spring and just got the plugs(Champion) and the Lisle backup tool. I'm off in two weeks for a week so it'll be a good time to have a go at it. Only 65K on the truck but I'd rather get this out of the way and off my mind. I'm going to do the overnight soak with the old standby WD40 and see how it goes. I'm thinking patience is probably your best friend and you can't be in a hurry with this one. I'm also going to buy new boots to install when I'm done. I'll post my results when I"m done.
